Carbon Calculator
The number of
possible perameters and variations means that
calculating your personal carbon footprint can
never be exact.
However it is
possible to give an approximation using the table
below. The table has been prepared on the
assumption that you make only one return air flight per
year. Try to assess your personal lifestyle
against the information in the columns.
The UK typical
footprint is about 11,100 kilogrammes of carbon
dioxide per person per year. That figure can be
compared on the table below. If everyone in the
world had a typical UK lifestyle we would need
2.7 planets!

Trees produce oxygen
in various amounts depending on the type of tree,
the season, and their age. Generally speaking,
deciduous (broadleaf) trees, (which are the type
we plant at Butterswood Farm), work harder and
produce more oxygen than coniferous (evergreen)
trees. A healthy young tree produces more oxygen
than a mature tree whose growth rate has slowed.
However slower
growing trees such as oak and maple have longer
lifespans and produce oxygen for a greater number
of years, so their net benefit could be greater
than some faster growing trees.
On average, one tree
produces about 120 kilogrammes of oxygen per
year. That means that a person with a `very
green' lifestyle, on the bottom (row 5) of the
table above would need the oxygen from 20 trees
to counterbalance their carbon dioxide
production!
